Device for dispensing predetermined quantities of liquid



May 14, 1963 N. L. PADZIESKI DEVICE FOR DISPENSING PREDETERMINEDQUANTITIES OF LIQUID Filed Dec. 5, 1960 a R m $4 m m 3 7 m m V I M I I Il l l l l I l w A i States This invention relates to containers of theflexible Wall type and aims to provide a predetermined portiondispenser, which may be applied in lieu of the container closure foraccurately dispensing a predetermined quantity of the material withinthe container.

An important object of the invention is to provide a dispenser fordispensing a measured quantity of material, wherein a surplus quantityfed into the measuring compartment will be returned into the container,thereby insuring an accurate measurement at all times.

Other and further objects and advantages of this invention will behereinafter described and the novel features thereof defined in theappended claim.

In the drawing:

FIGURE 1 is an elevational view of the measuring cap, forming thesubject matter of the present invention.

FIGURE 2 is a vertical sectional View through a container, and measuringcap, the sectional view of the measuring cap being taken on line 2-2 ofFIGURE 1.

FIGURE 3 is a sectional View taken on line 3-3 of FIGURE 2.

Referring to the drawing in detail, the container of the flexible walltype, is indicated generally by the reference character 5 and isprovided with the usual neck 6 tormed with external threads 7 on whichthe usual threaded cap is secured.

The device forming the subject matter of the present invention comprisesa tubular body portion 8 which is provided with a partition 9, dividingthe tubular body portion into an upper measuring chamber '10 and aclosure chamber 11, the closure chamber having threads formed in thewall thereof to cooperate with the external threads 7 in securing thetubular body portion on the neck of a container, in lieu of theconventional threaded closure.

The partition 9 is formed with an opening, through which the tube 12extends, the tube being of a length to extend to a point adjacent to thebottom of the container as indicated by FIGURE 2 of the drawing, whereit is beveled as at 13 to allow the contents of the container to passfreely into the tube 12.

The other end of the tube 12 extends laterally at '14 where it is alsobeveled providing a discharge nozzle which discharges material from thecontainer, at a point adjacent to the wall of the upper measuringchamber 10.

The outer or discharge end of the upper measuring chamber is normallyclosed by means of the hinged closure 15 which has a hinged connectionat 16. The closure 15 is formed with a snap tastener 17 that holds theclosure in a closed position, against accidental movement.

Extending from the closure, is a finger piece 18 for effecting openingor the closure 15, when it is desired to dispense the contents of themeasuring chamber.

atent ice It might be here stated that the nozzle of the laterallyextended end of the tube 12 is disposed towards the hinge of the closure15, thereby preventing excess liquid from passing through the nozzle '15during the discharge of the material from the measuring chamber, sincethe laterally extended end of the tube 12 will be disposed upwardlyduring the pouring operation. It will also be noted that because of theconstruction and location of the laterally extended end 14, the contentsof the bottle or container will be directed towards the side or wall ofthe measuring chamber, rather than directing the material outwardlyagainst the cap. It will of course be understood that it is within thescope of the invention to provide these caps of various sizes fordispensing various predetermined quantities of liquid, therebyeliminating waste of material which is packaged in containers or bottleswhich necessitate the tipping of the containers or bottles, to dispensethe liquid.

It is further pointed out that the liquid may be dispensed inpredetermined measured quantities while the container is held in onehand and pressure is directed to the flexible wall container with thehand holding the container.

It is believed that in view of the tforegoing description and disclosurein the drawing, the construction and operation of the present inventionwill be obvious, and that a further description is unnecessary.

What is claimed is:

A device for dispensing a predetermined quantity of a liquid adapted toseat in the mouth of a vertical flexible walled container, comprising anopen ended cylindrical body, a partition extending transversely withinsaid body and dividing said body into an upper measuring chamber and alower closure section, said closure section having internal threadsadapted to engage external threads surrounding the neck of thecontainer, said partition contacting and closing the said mouth of saidcontainer, an elongated tube extending through the said partition anddisposed axially of the said partition and said container, the lower endof said tube terminating adjacent to the bottom of said container, theupper end of said tube having a bevelled end with the bevel directedtoward said partition and being laterally disposed at right angles andterminating adjacent the upper end of said measuring chamber, and spacedfrom the side wall thereof and a hinged closure normally closing themeasuring chamber, the upper end of said tube being directed toward thehinged edge of said closure.
